Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The device is nibble (4-bit) controlled. Each nibble has separate 3-STATE control inputs which can be shorted 2.5 ns max for 3.0V to 3.6V V CC together for full 16-bit operation. Power-off high impedance inputs and outputs The 74VCX16244 is designed for low voltage (1.2V to Supports live insertion and withdrawal (Note 1) 3.6V) V applications with I/O capability up to 3.6V. CC Static Drive (I /I ) OH OL The 74VCX16244 is fabricated with an advanced CMOS r24 mA 3.0V V CC technology to achieve high speed operation while maintain- ing low CMOS power dissipation. Uses proprietary noise/EMI reduction circuitry Latch-up performance exceeds 300 mA ESD performance: Human body model 2000V Machine model 200V Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to V through a pull-up resistor the minimum CC value of the resistor is determined by the current-sourcing capability of the driver.
